Abstract
The bicycle with improved chain drive for turning of the utility model belongs to the technical field of human powered land vehicle, which is characterized in small front wheel, big back wheel, lower vehicle frame with handlebars arranged on the upper part of the frame crossbeam. The front wheel is indirectly driven to turn by the chain, and a person rides the bicycle in a sitting-lying posture, when shutting-down, both feet of the person can naturally touch down meanwhile. The utility model has the advantages of safe and comfortable ride, better maneuverability and high speed reaching 40 kilometers per hour.
Description
The utility model belongs to land manpower transportation field, is the improvement to the chair bicycle structure.
Chair bicycle has increased the distance of people and front-wheel, operability and bad stability when making the direct control front-wheel steering owing to prolonged the car crossbeam.
In order to address this problem, common way is to adopt the mode of indirect drive front-wheel steering.Proposed the double chair bicycle of a kind of practical high speed in the Chinese patent application 882045539 of my former application once, can address the above problem to a certain extent, but its handlebar is in the crossbeam bottom, because inertia, the people falls down easily during brake.In addition, steering hardware is owing to adopt the steel wire transmission, and steel wire weares and teares easily and comes off, so safety is relatively poor.I propose a kind of chain gear again and turn to chair bicycle in Chinese patent application 932470033, it can effectively solve problems such as road-holding property difference and poor stability, but this structure is comparatively complicated, and it is not too convenient to get on or off the bus.
The purpose of this utility model is to provide a kind of improved type chain gear to turn to chair bicycle, and it can effectively improve road-holding property, stability and the traveling comfort of riding, and steering hardware is simple and reliable, and it is comparatively convenient to get on or off the bus.
The utility model only needs to stand the sleeve pipe rear portion and welds a handlebar sleeve pipe abreast before original chair bicycle vehicle frame, and each fixes a sprocket wheel on vertical tube of front fork upper end and stem, connect rotation synchronously by chain between two sprocket wheels, reach the purpose that turns to, so structure is simple and reliable especially.The angle of inclination that its point of view is to make upright sleeve pipe before the vehicle frame with the ordinary bicycle vehicle frame before the angle of inclination of upright sleeve pipe identical, simultaneously again by the chain gear structure, with the close vehicle seat of handlebar, so the road-holding property of the present utility model of riding is the same with ordinary bicycle with alerting ability.
The utility model has two wheels, and front-wheel is little, and trailing wheel is big, and the people adopts and sits the posture lie by bike, and the walking vehicle handle is comfortable as driveing a car.There is back rest supports the vehicle seat back, is convenient to bring into play the power of pedaling of leg, can give full play to people's strength, improves the speed of a motor vehicle.In addition, vehicle frame is very low, and crossbeam is bent downwardly, and gets on or off the bus easily, and during parking, people's both feet can land simultaneously, are not easy to fall down, and safety is guaranteed.Body gravity is low simultaneously, and it is more stable to ride.One fairing is arranged above the car front-wheel, can reduce air resistance, help improving the speed of a motor vehicle.The utility model riding safety is comfortable, and road-holding property is fine, the time scooter more than 40 kilometers/hour.
Concrete structure of the present utility model is provided by following explanation and accompanying drawing, and Fig. 1 is the lateral plan that the improved type chain gear that the utility model proposes turns to chair bicycle.Fig. 2 is the block diagram that removes behind the fairing, and Fig. 3 is the block diagram of setting up behind the fairing.
The utility model vehicle frame adopts lower bent cross beams, cross sill is two-tube, the rear portion of upright sleeve pipe (1) before vehicle frame, weld a handlebar sleeve pipe (5) abreast, handlebar is on crossbeam top, and stem (6) passes handlebar sleeve pipe (5), fix a sprocket wheel (4) in stem (6) upper end, a sprocket wheel (2) is also fixed in the vertical tube of front fork upper end, connects rotation synchronously by chain (3) between sprocket wheel (2) and the sprocket wheel (4).The number of teeth of sprocket wheel (2) and sprocket wheel (4) equates.
Annotate: the numeral in the above narration is the label in the accompanying drawing.
Claims (2)
1, the improved type chain gear turns to chair bicycle, and this bicycle has two wheels, and front-wheel is little, trailing wheel is big, the people adopts and sits the posture lie by bike, it is characterized in that vehicle frame adopts lower bent cross beams, and cross sill is two-tube, the rear portion of upright sleeve pipe (1) before vehicle frame, weld a handlebar sleeve pipe (5) abreast, fix a sprocket wheel (4) in stem (6) upper end, a sprocket wheel (2) is also fixed in the vertical tube of front fork upper end, connect by chain (3) between sprocket wheel (2) and the sprocket wheel (4), rotate synchronously.
2, bicycle according to claim 1 is characterized in that the number of teeth of sprocket wheel (2) and sprocket wheel (4) equates.
